A joke ?

Does a program like this deserve to be on the appstore ??
It looked promising, having to buy for compilations is okay, but there are SO MANY limitations that it turns into a joke.. Maximum running time 15 seconds ?? What good is it then ? And there are no indications that if you pay those restrictions will be lifted..
The author has a lot of nice programming apps on the store, all set up with the same highly misguided principle - do you REALLY want serious customers, or is it all just for show ?
